HYDROCARBON-VAPOR S'TOVE.

SPECIFICATION forming part of Letters Patent No. 68 2,630, dated September 17, 1901.

Application filed March 6 1901. Serial No. 50,003- (No model.) v

To all whom it may concern:

3e it known that I, EDWIN G. MUMMERY, a c tizen of the United States, residing at Detro1t, county of Wayne, State of Michigan, have invented a certain newand useful Improvement in Hydrocarbon -Vapor Stoves; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art' to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object certain new and useful improvements in hydrocarbonvapor stoves, and has special reference to the provision of such a stove with a warmingcloset.

I carry out my invention as more fully hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a view in perspective showingone end or side of the stove removed to show the interior of the warming-closet. Fig. 2 1s a view in vertical cross-section showing parts in elevation. Fig. 3 is a detail view showing the burner and adjacent portions of the top of the warming-closet in vertical section. Fig. 4 is a plan view of the top plate of the stove, the grates being removed.

One of the purposes of my present invention is to locate a burner wholly within the warming-closet, the closet and burner being so arranged as to confine the heat radiating laterally and downwardly from the burner wholly within the closet.

Another object of my present invention is to more thoroughly protect the burner from air-drafts, and thereby to secure a steady and more effective operation of the burner.

Another feature of my present invention consists of the special construction of the top of the closet, as also the top of the stove, whereby any matter boiling over or falling through the grates above the burner, as in cooking, for example, will be prevented from entering the warming-closet and may very readily be removed, the whole top of the varmingcl'OSet being readily accessible and so shaped as to prevent any such matter interfering with the operation of the burner,

and whereby the top of the warmingcloset may readily be cleansed.

In the drawings, a represents a stove of this description, which may be of any desired construction, except as hereinafter specially described. The stove is formed with a warm ing-closet, (indicated at 7),) in which is located a burner c. The burner may be of any suitable construction. I prefer, however, and have shown in the accompanying drawings, a burner constructed in correspondence with a certain invention embodied in an applica tion now pending in the United States Patent Oflice, Serial No. 30,898, filed September 24, 1900, and which will need no further description herein.

The top of the closet is indicated at d, the same being made of curved form, arching upward, as shown, and being provided with an opening or openings for one or moreburners 0, located beneath said openings, and whereby the heat and flame passing upward from the burner may pass therethrough.

The top of the stove is indicated at e, the same being constructed, preferably, with an elongated opening, (indicated at f,) in which may be located grates, (indicated at gg.) I have shown in Figs. 1 and 4 the top plate 6 constructed for a stove having two burners j but I do not. limit myself to any particular number of bu rn'ers to be employed in connection therewith. The shape of the openingf of the top platee of the stove would of course be changed where only one burner was provided. The grate or grates g g are constructed simply to rest upon the top plate, as upon a flange h of the top plate, so that said grates may readily be removed when desired. The burner may be supported in place within the Warming-closet in any suitable manner, as upon supporting-bars it, which supportingbars may be attached to the frame of the stove in any desired manner and also to the burner in any suitable manner. The burner may for this purpose be provided with downwardly-extending lugs j j. In the opening or openings in the top of the warming-closet is located a collar is for each of the burners,"

The collar is preferably constructed also with a down wardly-proj ecting flange m, projecting downward about the outside of the upper portion of the burner, said collar closing the corresponding opening in the top of the warming-closet, about the upper end of the burner, to prevent the passage of air through the opening in the top of the closet, about the upper end of the burner. The flange Z of the collar rests by the gravity of the collar upon the adjacent portion of the top of the closet, and it is obvious may be moved to correspond with the required location of the burner to effect the closing of the said opening. By shifting the collar 7a to correspond with the location of the burner the closing of the opening in the top of the closet may readily be effected.

\Vhile it is believed to be unnecessary to go into a particular description of the particular burner shown and described, the same is provided with foraminous walls 1 2 3 4, said walls being preferably formed of cast metal, kerfed, as at 5. The walls being thus made of heavy cast metal, it is obvious that when heated a considerable amount of heat will be radiated laterally and downwardly into the warming-closet, while the flame and heat rising through the burner and above the top of the closet will act upon a utensil upon one of the grates g. The top d of the closet is preferably formed with troughs n, extending lengthwise of the stove and the entire length thereof, the arc-shaped portion of said top causing anyliquid or other matter spilling or boiling over from a utensil upon a stove to be directed downward to the sides of the top d and into said troughs, from which such foreign matter may readily be removed. The

closet may be constructed in any suitable manner to admit a supply of oxygen or air thereinto to support combustion in the burner. To this end, as shown, the back of the closet may be formed with an opening (indicated at p) for the admission of air into the closet. The closet is placed a little below the top of the stove, leaving an open chamber q between the top of the closet and the top 6 of the stove. This chamber q being open, air will readily be admitted thereinto to assist combustion taking place above the closet. It will be perceived that the burner is constructed with air-chambers 6, open at the base thereof, and with combustion-chambers 7, permitting a supply of air to pass upward through the burner.

WVhat I claim as my invention is 1. The combination with a hydrocarbonvapor stove provided with a top, of an open chamber immediately beneath said top, a warming-closet located beneath said open chamber, and a burner within said Warmingcloset, said burner and the top of said closet constructed to confine the heat passing laterally and downwardly through the burner within the closet, and permitting the heat passing upward through the burner to be clirected into said open chamber, said closet constructed to permit the inlet of asupply of air to assist in supporting combustion.

2. The combination with a hydrocarbonvapor stove formed with a top, of an open chamber immediately below said top, a warming-closet below said open chamber having an opening in the top thereof, and a burner located in said closet beneath the opening in the top thereof, said burner and the top of said closet constructed to close said opening about the outside of the upper end of the burner, and to restrict the heat passing laterally and downwardly through the base of the burner and confine it within the warmingcloset.

3. The combination with a hydrocarbonvapor stove formed with a top, of an open chamber immediately below said top, awarming-closet below said open chamber having an opening in the top thereof, and a burner located in said closet beneath the opening in the top thereof, said burner and the top of said closet constructed to close said opening about the outside of the upper end of the burner and to restrict the heat passing laterally and downwardly through the base of the burner and confine it within the warmingcloset, the top of the warming-closet being elevated at the longitudinal center thereof.

4. The combination with a hydrocarbonvapor stove formed with a top, of an open chamber immediately below said top, a warming-closet below said open chamber having an opening in the top thereof, and a burner located in said closet beneath the opening in the top thereof, said burner and the top of said closet constructed to close said opening about the outside of the upper end of the burner and to restrict the heat passing laterally and downwardly through the base of the burner and confine it Within the warmingcloset, the top of the Warming-closet being elevated at the longitudinal center thereof, the longitudinal edges of the top of the warming-closet being trough-shaped.

5. The combination with a hydrocarbonburner provided with a top, of an open chamber immediately below said top, a warmingcloset having an opening in the top thereof located beneath said open chamber, a burner within said warming-closet beneath the opening in the top thereof, and a collar located between the ontside of the top of the burner and the adjacent edge of the opening in the top of the closet to close said opening about the outside of the burner at the upper end thereof, the base of the burner communicating with the interior of the closet, and the top of the burner communicating with the open chamber thereabove.

In testimony whereof I sign this specifica tion in the presence of two Witnesses.
